A Southern Californian mother of four accidentally dropped an extra dollar in the machine when she decided to buy a lotto ticket—and it turns out that was a good thing.

Instead of flushing a dollar down the drain, Thuan Le won $14 million by sheer mistake at a Mission Viejo, Calif. CVS. Typically, she spends about $5 on Lotto tickets. This time she dropped in an extra dollar by accident when she went for her regular routine.

According to NBC, Le decided to take her chances. Turns out, that extra SuperLotto Plus ticket was the winning ticket.

She checked the ticket with a friend, and once she realized what had happened, she ran screaming in joy from the store and called her sons. She then drove straight to the California Lottery’s Santa Ana office near her home to claim the prize.

“We thought she was joking,” her son told Lotto officials, “but we thought would she really joke like this? My older brother said, ‘yes, she would.'”
